Abstract
An anomaly determination method of the present embodiment includes: measuring a first resistance value of a processing target via a first grounding member when the first grounding member is attached to the processing target in a first chamber; bringing the first grounding member into contact with a grounded second grounding member to measure a second resistance value of the processing target via the first and second grounding members in a second chamber; and determining an anomaly of the second grounding member with an arithmetic processing unit based on a trend of a resistance difference between the first resistance value and the second resistance value for a plurality of processing targets.
